Recently I discovered the MOC atlas and I have found this to be quite a work of art with the surface of Mars looking like a painting. http://mars.asu.edu/data/moc_256/
Unfortunately I am having a hard time locating a color map of MOC WA images which utilized the red and blue filters. Does there exist one or not really?

Thanks, I'm pretty proud of that. Unfortunately I was never able to complete a color version. For one thing, the WA blue geodesy campaign coverage was noisy and incomplete. It ended up being taken at half the resolution of the red images and was even harder to remove photometric signature from.

The merged MOLA/MOC image that went into https://tharsis.gsfc.nasa.gov/ngs.html was colorized from a color global map mosaic assembled by hand by Mike Malin.

I know there's been some more recent work on the MOC WA dataset by a few people, for example https://ui.adsabs.harvard.edu/abs/2020JGRE....06231R/abstract but I'm not aware of anything like a native-resolution WA color mosaic. It would be a big task, trust me.

After 200 hours, I managed to remove most of the artifacts from the Mars MOC mosaic and synthetically colorize it. A couple dust storms were somewhat removed with Viking mosaic and Hellas was darkened to better match albedo.
This is a 2K sample of the 16K sample on my flickr of the 64K texture I made for Celestia:

the moc256 data was what i used for my colorized map of mars
and used the color data from a surviving map i had ( lost ALL , well 99.9% of my old data do to a drive crash)
the surviving map was a 8k map from MSSS data ( Hellas was darker in that set of data)

glad to see you cleaned up the data a bit .
